This application claims priority to and is a divisional of co-owned co-pending U.S. patent application Ser. No. 10/899,915, filed Jul. 27, 2004, which is incorporated herein by reference in its entirety.
The description herein relates generally to portable computers, and more particularly to portable computer hinge caps.
Portable laptop or notebook computers include a base and a top which is pivotally connected to the base at a hinged connection. When the top is raised, a display panel such as a liquid crystal display (LCD) panel mounted therein is exposed. The top of a portable computer is typically connected to the base by a hinge on one edge and by at least one latch located on at least one other edge. When unlatched, the top is rotated open thus exposing a keyboard on the base and the LCD panel mounted in the top. The latch which secures the base and top is typically mounted along an edge of the top.
Some hinge assemblies have been provided with clutch mechanisms. Such clutch mechanisms can include a friction component and a torsion spring component. The spring counteracts the weight of the display housing when the display housing is open, such that the friction component need only be strong enough to support the open display housing during times when the computer is subjected to vibration or the like.
The clutch assemblies may be covered with hinge caps which are often used when a chassis has clutch assemblies that reside in the far end corners of the chassis and are positioned adjacent the LCD display. One disadvantage of current hinge caps is that they are separate parts which often become loose resulting in movement and noise when the top portion is rotated open or closed. In some cases, the hinge caps can fall off or break off. There may also be alignment issues with mating parts resulting in fit and finish problems.
Some hinge caps are glued or heat staked into the chassis or the clutch. The glue may not adhere to mating metal parts due to machine oil or internal lubrication contamination. Heat stakes may break off or fall off if they become loose.
Accordingly, what is needed is a hinge cap solution which is free of the disadvantages described above.
In one embodiment, accordingly, there is disclosed a hinge interconnecting a first member and a second member. The hinge includes a hinge portion having a pair of external opposed grooves and a first locking portion. A hinge cap is removably attached to the hinge portion by a pair of external deflecting arms received by the opposed grooves and a second locking portion received by the first locking portion. In response to mounting the hinge in the first member, the hinge cap seats in and defines a gap with a cover plate on the first member.
For purposes of this disclosure, an information handling system (“IHS”) includes any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. Example of an IHS include, personal computer (“PC”), a network storage device, personal digital assistant, or any other suitable device with variations in size, shape, performance, functionality, and price. An IHS also includes other components such as, random access memory (“RAM”), one or more processing resources (e.g., central processing unit (“CPU”), hardware or software control logic, read only memory (“ROM”), other types of memory, one or more disk drives, one or more network interfaces, one or more input/output devices and/or one or more buses.
Chipset 110 further acts as a controller for main memory 115 which is coupled thereto. Chipset 110 also acts as an input/output (“I/O”) controller hub (ICH) which performs I/O functions. General purpose input/output (“GPIO”) 160 is coupled to chipset 110 via GPIO controller 165. USB controller 170 is coupled to chipset 110 so that devices such as USB devices 175 can be connected to chipset 110 and processor 105. USB devices 175 include, for example, floppy disk drives, CD-ROM drives, DVD-ROM drives and other devices which support the USB standard. System basic input-output system (“BIOS”) 140 is coupled to chipset 110, as shown. BIOS 140 is stored in CMOS or FLASH memory so that it is nonvolatile.
Local area network (LAN) controller 145, alternatively called a network interface controller (NIC), is coupled to chipset 110 to facilitate connection of IHS 100 to other information handling systems. Media driver controller 150 is coupled to chipset 110 so that devices such as media drives 155 can be connected to chipset 110 and processor 105. Examples of media drives 155 capable of being coupled to the media controller 150 include CD-ROM drives, DVD drives, hard disk drives and other fixed or removable media drives. Expansion bus 120, such as a PCI bus, PCI Express bus, serial advanced technology attachment (SATA) bus or other bus is coupled to the chipset 110 as shown. Expansion bus 120 includes one or more expansion slots 122 for receiving expansion cards which provide IHS 100 with additional functionality. IHS 100 also includes speaker (e.g., loudspeaker) 138 for outputting audio signals. Speaker 138 is coupled to chipset 110.
In one embodiment, illustrated in
A hinge cap 222 is provided for each hinge 208 adjacent chassis cover plate portion 216. The hinge cap 222 provides an aesthetic appearance to chassis 206.
Referring now to
A portion of each hinge 208 is within chassis 206, and is covered by a hinge cap 222. With hinge cover 218 removed, a portion of a circuit board 240 is visible.
Referring now to
Referring now to
Hinge cap 222 is releasably attached to middle portion 312. Hinge cap 222 includes a cosmetic top portion 324 and a bottom portion 326. Bottom portion 326 includes a pair of deflectable arm portions 328 which are received within groove 316 of middle portion 312. Each deflectable arm portion 328 includes a male connector (not shown) which can slide through groove 316 and over protrusion 318 by bending deflectable arm portion 328, and then be received by female connector 320. To release hinge cap 222 from hinge 208, deflectable arm portion 328 can be bent outwards to disengage the male connector from female connector 320, and then can slide out of groove 316.

Referring now to
Hinge 208 includes top portion 310, middle portion 312, and post portion 314. Top portion 310 includes cylindrical opening 421. Middle portion 312 includes grooves 316. Grooves 316 include protrusions 318 and female connectors 320. Post portion 314 includes connectors 419, adapted to connect to a portable IHS chassis or top panel.
Hinge cap 222 includes cosmetic top portion 324 and bottom portion 326. Bottom portion 326 includes deflectable arm portions 328. Deflectable arm portions 328 are adapted to be received within grooves 316, respectively. Deflectable arm portions 328 include male connectors 530, adapted to be received by female connectors 320, respectively.
Clutch assembly 220 includes screw holes 642 and positioning pin holes 644, adapted to connect clutch assembly 220 to a portable IHS chassis or top panel. Clutch assembly 220 also includes shaft 646 received within cylindrical opening 421. Shaft 646 rotates within cylindrical opening 421 to allow clutch assembly 220 to rotate relative to hinge 208.
To engage hinge cap 222 with hinge 208, hinge cap 222 is moved in the direction of arrow 660 while deflectable arm portions 328 are received within grooves 316. Hinge cap 222 is moved until male connectors 530 of deflectable arm portions 328 move over protrusions 318, and snap into and engage female connectors 320, respectively. The result is a sliding and snap-in engagement of hinge cap 222 and hinge 208. Although the hinge cap 222 is snapped into engagement with hinge 208, the hinge cap 222 is in a loose or floating engagement with the hinge 208. A combination of features on the hinge cap 222 and on the chassis cover plate 216 can provide the X, Y and Z location of the hinge cap 222 relative to the chassis cover plate 216. For example, when the hinge 208 is mounted in the chassis 206, at least three sides of the hinge cap 222 engage the chassis cover plate 216, as is best shown in
To disengage hinge cap 222 from hinge 208, deflectable arm portions 328 are bent outwardly to disengage male connectors 530 from female connectors 320. Hinge cap 222 is then moved in a sliding manner in the direction opposite of arrow 660, until deflectable arm portions 328 are no longer received within grooves 316.
Although illustrative embodiments have been shown and described, a wide range of modification, change and substitution is contemplated in the foregoing disclosure and in some instances, some features of the embodiments may be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be constructed broadly and in manner consistent with the scope of the embodiments disclosed herein.
